The Android Operating System introduces Smartphone users to an entirely new world of possibilities, and the option to root an Android device so that root apps, custom kernels and custom ROMs can be installed onto it only adds to these possibilities. However, after rooting their device and installing SuperSU (the most popular of the array of Superuser management applications available on the Play Store), many an Android user has been greeted with a mysterious error that reads “Unfortunately, SuperSU has stopped”. This error force closes the SuperSU app and can prove to be quite troublesome for users who want to go above and beyond with their Android device.
This error is most commonly caused by a corrupted installation of SuperSU or corrupted Super SU binaries. Most people who go through the trouble of rooting their Android device certainly want to go all the way, which is why people who root their devices and receive this error want to get rid of it immediately. Well, the following are the steps a rooted Android user needs to follow in order to fix the “Unfortunately, SuperSU has stopped” error, once they have uninstalled the previous installation of SuperSU, of course:
a) SuperSU has multiple update packages, with new packages being released by Chainfire on a pretty frequent basis. The first step a rooted Android user needs to go through in order to get rid of the “Unfortunately, Super SU has stopped” error is to download the latest SuperSU update package.
b) Copy the .zip file to the device.
c) Flash the .zip file onto the device using any custom recovery tool (CWM or TWRP, for example).
d) Go to the Google Play Store and look for and reinstall the Super SU app.
e) Reboot the device, and once the device has booted up, the “Unfortunately, SuperSU has stopped” error should not longer persist.
